Bright light therapy has been used to safely and effectively treat conditions such as Seasonal Affective Disorder and to regularize sleep in patients with circadian rhythm disorder. Based on evidence of the link between bright light, serotonin, mood and carbohydrate metabolism, it has been suggested that bright light therapy can improve weight loss but the literature on the subject is sparse. Further, the literature suggests that apart from any changes in mood and carbohydrate metabolism, bright light may reduce the unpleasant side-effects of exercise and increase compliance to an exercise program.
Objective: Increased physical activity is important given the concern over the growing rates of obesity. Bright light therapy has the potential to enhancing serotonin levels, impact on carbohydrate metabolism and reducing soreness and hyperthermia associated with physical activity. The aim of this study is to conduct a controlled investigation of the effects of bright light therapy and exercise on weight loss and body composition in overweight individuals.
Research Methods and Procedures: Twenty-five overweight male and female subjects will be assigned to 6 weeks of moderate exercise with or without bright light treatment. Outcome measure included changes in body mass and body composition and ratings of mood, seasonality and sleep.
